Unified API Elizabeth line live arrivals duplications

1

Note for anyone using the Elizabeth line live arrivals from Unified API

Liverpool Street has one CRS code (“LST”), but 2 ATCO codes:

National Rail/Overground platforms: 910GLIVST
Elizabeth line platforms: 910GLIVSTLL

When you call Unified API for live arrivals for either of the ATCO codes we will return live arrivals for the CRS code LST, which will give a full set of arrivals including National Rail/Overground and also Elizabeth line.

If you call Unified API for both ATCO codes you will get a duplicate set of results. So you only need to call for one of the ATCO codes.

It’s similar with Paddington. This also has 2 ATCO codes:

National Rail: 910GPADTON
Elizabeth line: 910GPADTLL

Again, if you call live arrivals for either ATCO code you will get a full set of live arrivals for the CRS code “PAD”.

Hope this helps, let me know if any questions. Thanks.

Thanks for the post. I’ve got exactly this problem, I’m combining two ATCO codes for Liverpool Street, Paddington and Whitechapel but get duplicated arrival predictions for the 3 stations. I was about to post about it. I guess I just need to ignore one of the ATCOs per station.

I’ve done this to get them to work for me…

const ELIZABETHSTATINS = ["WHX", "LSX", "FDX", "WWC", "ABX", "PDX",];
const MERGESTATION = ["ABW" => "ABX", "ZLW" => "WHX", "LST" => "LSX", "ZFD" => "FDX", "PAD" => "PDX"];

to get the mapping to work, but since I did this Darwin has removed the “new codes” from the data from the Pushport.

I guess this means that the “…X” codes are no longer required.
